But in the world's speediest recovery, Rihanna is back - attending the premiere of Battleship in LA last night.

She even had enough energy to do the coolest red carpet pose on the block - as favoured by Kate Middleton and Angelina - by thrusting out her leg from beneath her dress. Foxy.

So that's one party, one trip to hospital, and then straight back to a premiere. Whatever was in that drip must have been seriously effective.

Yesterday we revealed a video of Rihanna talking about breaking down under the pressure in the past.

In this new interview titled ‘Road To Talk That Talk’ – recorded at the beginning of the year – Rihanna was asked how hard she worked on her sixth album.

She said: “It was the best sh*t ever, it was some rock star sh*t. This is the craziest schedule I’ve ever been on in my entire life.

“One morning I woke up and started crying so hard. I finally just got to my bed from the IV [drip] and I was just like, ‘Good I can actually get to sleep tonight’ because we stayed up [all night’ and I finished [the album] at 5pm the day before.

“So now I’m like ‘One good night of rest.’ I get in bed and it must have been two hours in before my phone started going off.

"“I was so frustrated I kept ignoring the phone. Every time it would go off but every time I would ignore it. But it would be another burden on my shoulders ‘cause I know it has to get done.”

“I know I’m sick but I’m the only person who can get it done so it was so frustrating so I was angry. I was so angry, I was so overwhelmed that I was sick it felt crazy.

“I started crying. I cried for 10 minutes really, really hard in my pillow. It was aggressive. I don’t cry loads. If I cry it’s because I’m very angry and I can’t do anything about it, because I’ve run into a dead end that’s when the tears would come down. But this time I needed to hear it, I almost wanted to punch somebody.”
